US President Donald Trump called for Ukrainian President Volodymyr Zelensky to leave office, arguing that Ukraine’s leader has repeatedly rejected opportunities to negotiate an end to the war with Russia.

“I think it’s time for Ukraine to get a new president,” Trump told reporters outside the White House on Saturday. “I suggest they get a new leader who can make a deal,” he said, adding: “For some reason he never does.”

Trump also urged Kyiv to stop striking Russian oil refineries, claiming the attacks were contributing to a worldwide diesel shortage and increasing expenses for American farmers and ranchers. “He better damn well stop,” Trump said.

His comments came a day after he unexpectedly announced a diesel supply arrangement with Russian President Vladimir Putin. Under the proposed deal, Russia would deliver more than 300,000 tons immediately, followed by 500,000 tons in November and another 1 million tons afterward. An additional 3 million tons would depend on the condition of Russian refineries.

The United States temporarily relaxed sanctions on Russian diesel exports to facilitate the shipments, easing restrictions originally imposed to limit the energy income Moscow uses to finance its war against Ukraine.

Zelensky told Axios that the arrangement had taken him by surprise, calling it “not fair and not honest” and describing it as an unjustified concession to Putin.

According to Axios, citing a US official familiar with the matter, Trump pursued the agreement after Zelensky disregarded six American requests to stop attacks on Russian refineries. Kyiv had proposed a mutual suspension of such strikes, with Zelensky telling Trump and his envoys, Steve Witkoff and Jared Kushner, that Ukraine would cease targeting Russian refineries if Moscow stopped attacking Ukrainian power plants.

A Ukrainian official separately told Axios that Witkoff and Kushner had threatened to suspend US intelligence sharing if Ukraine continued the attacks. However, a US official disputed that account, saying the envoys had stressed Washington’s military assistance to Kyiv while encouraging Ukrainian leaders to avoid actions that could raise costs for American consumers.
